In 2004, Hubble created the Hubble Ultra Deep Field (HUDF), the deepest visible-light image of the Universe, and now, with its brand-new camera, Hubble is seeing even farther. This image was taken in the same region as the visible HUDF, but is taken at longer wavelengths. Hubble’s newly installed Wide Field Camera 3 (WFC3) collects [...]

A specialized camera on a telescope operated by U.K. astronomers from Liverpool has made the first measurement of magnetic fields in the afterglow of a gamma-ray burst (GRB). The result is reported in the Dec.10 issue of Nature magazine by the team of Liverpool John Moores University (LJMU) astronomers who built and operate the telescope [...]
